Cues in verbal exchanges
For body language; a shrug can display a meaning of cluelessness or disinterest. Vocal communication and sign language can be used to display much more complicated views and feelings that body language alone, however body language can be used to enhance communication. When referring to someone, pointing at them can help determine who it is; this is an example of vocal communication being enhanced by body language.
Positive and Negative Language is displayed through both the content of the language, the tone it is said in and the body language used. Positive and Negative language both have their respective uses but can convey a mixed or completely wrong message if they are used in the wrong scenario.
